Abstract
A search for high-mass resonances in the e+e- final state is presented based on 2.5  fb-1 of √s=1.96  TeV pp&#773; collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an e+e- invariant mass of 240  GeV/c2. The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 1501000  GeV/c2 is 0.6% (equivalent to 2.5σ). We exclude the standard model coupling Z′ and the Randall-Sundrum graviton for k/M&#773; Pl=0.1 with masses below 963 and 848  GeV/c2 at the 95% credibility level, respectively.
